v TYPE-WRITING MACHINE Specification of Letters Patent.

Patented July 21, 1908.

Application filed March 23 1908. Serial No. 422,709.

To all whom it may concern:

Be it known that I, OSCAR Woonwa-nn, citizen of the United States, and resident of. Montclair, in the county of Essex and State of New Jersey, have-invented certain new and useful Improvements in Type-Writing Machines, of which the'following 1s a specification.

My invention relates to typewriting 'ma-.

chines and more particularly to means operable at will for maintaining the types-out of :contact with the inking pad to facilitate the removal from and the introduction of an ink pad into the machine.

A The present invention is in the nature of an lmprovement on the construction dis-- closed in my prior application Serial No. 357 ,609; In t at construction and in all prior constructions,- so faras I- am aware, the type bars are all simultaneously moved away from the ink pa'd and all of the type'bars are given the same extent of movement. For

these reasons-"the type bars may be given but a very slight movement away from the ink pad without being broughtinto conflict.

. The main object of m resent invention is toovercome the above ii ficnlties :andto provide simple and efficient means for moving are away from the inkpad a suflicientistance to enable it'to be readily re- 'moved from the machine and without bringing the type bars intoengagement with one another. .i To the above'and other ends which will hereinafter appear, my invention consists in the various features of construction, arrangements of parts and combinations of-devicesto be hereinafter described'andpatticularly pointed outin the appended-claimaq f- In the accompany drawings wherein like reference characters indicate corresponding parts in the different views, Figure Li's-a."

a sufficient number front elevation of the means for locking the key levers depressed.

While I have illustrated my invention ap- I plied to a front strike typewriting machine embodying atype action of the same specific character as that disclosedin the application of George F. Ballou filed January 22, 1907,

Serial No. 353,558 and of the same general character as that shown in the application of Arthur W. Smith filed May 15, 1905, Serial No. 260,441, it should be understood that the invention may be applied to other styles of typ ewriting machines.

he frame of the machine comprises a base l corner posts 2 and a top plate 3. Any.

suitable carriage (not shown) is provided with a'platen 4, diagrammatically shown in Fig. 1,- the carriage traveling from side to side of the machine in the usual manner. A segment 5 has radially disposed hangers 6 secured thereto by screws 7. Each han er has a driver 8 pivoted thereto at ,9 an each driver is pivoted at 10 to a t e' bar roper 11. The forward end of one ar is nks of the system of type bars are pivoted on a pivot wire 14; each guide linkbeing received and ided in a radial slot 15 in asegpull link 17 is connected at its forward end-of the link being connected at 19 to a bell crank sub-lever 20. Thasub levers are each pivoted at 21- to a ,hanger22 secured he forwardly projectingerm of each bell crank sub-lever 20-is connected to the upper end of a link 25, the lower end of which 18 connected at 26 to :an associated key lever'27. The key levers '27"are all pivoted on a pivot rod 28 secured to depending arms 29 which form part of a a screws 35 to brackets'36 which project from the segment 34-. Brackets 37 are secured b Y screws 38 to theangular plate 34 near eac side of the machine and are provided with bearings 39 for the reception of a rock shaft guide 7' 40. This rock shaft is grooved throughout its length to receive a looking or depressor bar or plate 41 which extends substantially throughout the length of the rock shaft and throughout the width of the keyboard as shown in- Fig. 4.

The right-hand end of the rock shaft 40 is bent to forma crank arm 42 provided with a finger piece 43 by which the rock shaft may be turned in its bearings to move the locking bar to and from operative position. The inoperative position of the locking or depressor bar is shown in Fig. 1 and the operative position of the bar is shown in F1gs. 2' and 4.

The locking bar is apertu red near the righthand end thereofat 44 for, the-reception of' the'reduced end 45 of a leaf spring 46, the

' bar to maintain said bar in the inoperative.

position when it is turned tOSuCll position through an actuation of the finger piece 43 as indicated in Fig. 3.- This same spring like:

wise bears against the upper wall ofthe slot when the finger piece is turned to the osi-j tion shown in Fig. 2 tomaintain the loc ing bar against accidental displacement from the operative osition to which it may likewise be moved by the finger piece. The spring at this time exerts a pressure, towards the axis ofthe rock shaft, thustendin'gfto prevent the locking bar from being turned from the o erative position. The shoulders 46" on-t e spring 46 formed by the-reduced portion a ut the locking plate 41- at each side ofthe aperture 44 therein and limit the forward movement of the plate. 'It' will be understood that the types 48 normally bear against an inking pad 49 contained in a case 50 I which may be .detachably secured-to the inking frame of the machine. The inking pad maylikewise be detachablymounted in its troughlike case 50. One inking pad" may be re- .moved and another substituted therefor at will either-by removing the-inking ad from its case or by lifting the case and t e inkingpad together out of the machine and substia new pad for the one which is exhausted.

In order to facilitate the removal of the pad it is desirable or necessaryto remove a l the types 48 from contact with the inking pad. It is for this purpose that the so-cal ed locking bar'41 is provided. When thelocking bar is in the inoperative position shown in Fig. 1, the types normally rest on the ink pad and are free to be actuated and to moveto the printi position as indicated by the dotted-line in Fig. 1 at each depression of the key 30. Then it is desiredto remove .the inkinghpad the fingerpiec'e 43 is moved rearwardly' from the position shown in Fig. .1

to that indicated in Fig. 2. The effect of this movement is to turn the locking bar around an axis substantially .coincident with one edge thereof and to depress all of the key levers to, the-positions-shown in Fig. 2, thereby moving all of the jointedtype bars in radial planes a sufficient distance to carry the types out of contact with the inking padas shown in Fig. 2 to facilitate a removal of the.pad. When a new or re-inked ad has been introducedinto the machine t e linger piece 43 is again moved to the position shown in Fig. 1, thereby releasing all of the key levers and enabling the types 'to again contact with the From an inspectionof Fig. 4 it will be observed that the lower edge of the locking plate '41 is notched as indicated at 41 in order to provide contact faces which are situated at difierent distances from the pivotal axisfof the locking bar. In the present instance I have shown the locking bar notched so that the bottom walls of the notches cooperate with the associated key lever 27 whereas the projections between the notches in the bar co-act with alternate key levers.

[The object of thisarrangement is to enable a group comprising one-half of the key levers I to be taken up and moved'by the contact faces on the rejections of the locking bar before the ot er group comprising the remainin half of the key levers is taken up and moved y the notched ortionsof the looking bar. When the loc ing bar is moved to the operative position the effect of this is to first produce a movement of one-half of. the

type bars awa from the inkin pad and to then removet e other half of fire type bars away from, the inking dpad. The two groups of type bars are move away from the inking pad to difierent distances as shown in Fig. 2

wherein it will be seen that the upper set of I bars; which are first moved away from the pad by the projections on the lockin bar are moved 'to a greater extent than the ower set of bars shown in Fig. 2. In this manner the radially disposed bars of the two groups are moved successively away from the inking pad so that there is no conflictbetween the bars which move in'radially disposedplanes. towards each other.

Various changes may be made without departing from the spirit and scope of my invention.
